Follow the mystery
Longer stories and age-matched activities. Notice the clues and share ideas with the Crew.
From The Hello Stamp activity: “Design three greetings using faces and gestures. Teach your family your favorites.”
Think it through
Richer stories and a mystery they can work through more independently. More room for their own theories and written replies.
